WATER SPRINKLER.

Application filed November 3 1925. Serial No. 66,570.

To all whom it may concern:

Be it known that We, VVX LIAM G- TODD and JAMES WV. Poirnnor, citizensof the Dominion of Canada, residing atvictoria, in the Province of British Columbia, Canada,

have invented certain new and useful Improvements in vVate'r Sprinklers, of which the following is a specification.

This invention relates to a water sprinkler such as is used for irrigating purposes, and belongs to that class wherein an outwardly directed main jet or jets is slowly rotated to project its spray beyond that of a reaction sprinkler rotatable on the same axis.

The improvements are directed to the means whereby the main sprinkler head is slowly rotated by small increments fromthe rotation of the reaction sprinkler head.

The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. 1 is an elevation and part section of the sprinkler.

driving connection between the reaction sprinkler tubes and a main sprinkler tube in the direction of the arrow 2 in Fig. 1, and 2 Figs. native driving connections.

In these drawings 2 represents a stand pipe to which a supply of water under pres sure is delivered from a water service.

On this stand pipe 2 is secured a nipple 3, havinga shouldered reduction adapted to receive the collar 5 of a short hollow stem 6. On the upper end of this stem 6 is secured across 7 from the horizontal components of which extend each way the main sprinkling pipes 8, the outer ends of which are upwardly turned to the desired angle of projection and have a cap 9 apertured to deliver the desired spray.

In the'upper end of the cross 7 which is v in alignment with thestand pipe is a nipple 10 having a shouldered reduction at 11 adapted to form a seat for the collar 12 of a hollow stem 13 rotatable in the nipple 5O 10. On the outwardly projecting end of this stem 13 is secured a T 1 1 from which extends each way the horizontally disposed pipes 15 of a reaction sprinkler, the ends of which are upwardly and backwardly 2 is a sectional elevation showing the 1 3 and 4 show in similar views alterturned and are capped, with apertured ends 16.

The stem 6 of the main sprinkler 7 8, 9 is thus freely rotatable in the bearing 3 and the collar 5 of that stem constitutes an effective seal preventing the escape of the' water past the bearing, without any require ment of packing or a ground joint: And so with the stem 13 of the reaction sprinkler 14, 15, 16 which is independently rotatable in the bearing 10 which is secured to and rota-table with the. main sprinkler 7, 8, 9 and its stem 6, and the ends of the tubes 15 being backwardly turned this sprinkler is rotated by the reaction of its escaping ets.

Secured on one of the arms 8 of the main sprinkler to project upward from it is a member 17 in the upper end of which is pivotally mounted at 18 a lever 19. This lever 19 is checked in the upright position and is counter-weighted at 20 to normally maintain the end 21 in the path of the tubes 15 of the reaction sprinkler and to Offer a yield ing resistance to movement oif the check.

In the uprlght pos1t1o'n it will be engaged by the tubes 15 of the reaction sprinklen' which engagement owing to the yielding resistance, will move the main sprinkler 7, 8, 9 through a fraction of its rotation in the bearing 3 and at the same time will allow the tubes 15 to pass.

Figure 2 shows a counterweight 20 as af fording this yielding resistance. In'Figure 3 it is afforded by a spring 21 from a pin projecting from the lever 19"to one projecting from the hub of the i'ipwardly projecting member '17, and Figure 4 shows the yieldingresist-ance as offered by a spring 22 secured in and upwardly projecting from 17" with a sleeve 23 slidable between an upward'projection 2 1 from 17 and the spring 22 whereby the tension on that spring may be adjusted.

The substance of the invention resides in the simple provision whereby a relatively small rapidly rotating reaction sprinkler 14, 15, 16 may be applied to rotate about the same axis as the main sprinkler head 7, 8, 9, throwing a larger quantity of water and throwing it radially outward, that is, not checked by the requirement of the jets being directed backward to impart rotation.

The parts are simple to manufacture and to maintain and leakage past the bearing is effectively prevented without any requirement of gland packing or ground joints to impede rotation to add to its expense.

, Having now particularly described our invention, we hereby declare that what we claim as new and desire to be protected in by Letters Patent, is:

1. A water sprinkler of the class described, comprising in combination an upright pipe to which a supply of water under pressure is delivered, a hollow stem rotatably mounted in the upper end or the pipe from which stem a tubular arm laterally projects with a nozzle directed outward and upward from it to constitute the main sprinkler, a second hollow stem rotatably mounted in the upper end 01 the first nan'ied stem from which second stem the arms of a reaction operating sprinkler project, and a yielding projection secured on one of the sprinklers to en age an adjacent part of the other sprinkler whereby the rotation of the reaction sprinkler will more the main sprinkler through a fraction of its rotation on each engagement. 2. A water sprinkler or" the class described, comprising the combination with an upright pipe to which a supply of water under pressure is delivered, or a hollow stem rotatably mounted in the upper end of the pipe from which stem a tubular arm laterally projects with a nozzle directed outward and upward "from it to constitute the main prinkler, a second hollow stem rotatably mounted in the upper end'o'i the first named stem from which second stem the arms of a reaction operating sprinkler project, and a yielding projection from an arm ct one oi the sprinklers to engage a corresponding part of the other sorinkler whereby the rotation of the operating sprinkler will move the main sprinkler through a fraction of its rotation on each impact of the yielding projection. 3. A water sprinklerof the class described, comprising the combination with an upright pipe to which a supply of water under pressure is delivered, of a hollow stem rotatably mounted in the upper end of the pipe from which stem a tubular arm laterally projects with a nozzle directed outward and upward from it to constitute the main sprinkler, a second hollow stem rotatably mounted in the upper end of the first named stem from which second stem the arms of a reaction sprinkler project, and means projecting from one of the tubular arms of the main sprinkler to otter a yielding obstruction to movement of the reaction sprinkler past it, and by which the main sprinkler is moved through a fraction of its rotation on each engagement; v

A water sprinkler oi the class described, comprising the combination with an upright pipe to which a-supply of water under pressure is delivered, of a hollow stem rotatably mounted in the upper end of said pipe from which stem a tubular arm laterally projects with a nozzle directed outward and upward from to constitute the main sprinkler, a second hollow stem rotatably mounted in the upper end of the first named stem from which second stem the arms ot a reaction operating sprinkler project, and a yielding resistance secured on the arm of the main sprinkler and projecting upward from it to engage a passing part of the operating sprinkler whereby the arm of the main sprinkler will be moved through a fraction of its rotation for each rotation of the reaction sprinkler.

5. A water sprinkler of the class described, comprising the combination with an upright pipe to which a supply of water under pressure is delivered, of a reducing nipple secured on the upper end of the pipe, said nipple bored a bearing with a shoulder at the reduction, a hollow stem rotatably mounted in the bearing of the nipple with a collar seating in the shouldered reduction, said stein projecting beyond the upper end ot the nipple, tubular. arms secured to and in'ojec'ting horizontally from the stem, through which arms the main supply of sprinkling water is delivered, a second reducing nipple secured to the upper end of the hollow stem and in axial alignment with it, a second hollow stem rotatably mounted in this reducing nipple, said stem having a collar seated on the shouldered reduction of the nipple, a reaction sprinkler secured to and rota able with the second named hollow stem, and means for moving the main sprinkler through a fraction of itsrotation each time a tube of the reaction sprinkler,

passes a tube of the main sprinkler.

In testimony whereof we aiiix our signatures.
